Stilbite Radiating Crystal Cluster and Heulandite Cluster — India | 90 g | 7 × 7 × 4 cm

Stilbite & Heulandite — Natural Indian Mineral Specimen

This attractive natural mineral specimen features an intergrown Stilbite and Heulandite crystal cluster, representing one of the classic zeolite associations found in the basalt-hosted mineral cavities of Maharashtra, India. Stilbite and Heulandite commonly occur together in the Deccan Trap region, where mineral-rich fluids gradually filled cavities within basalt and allowed zeolite crystals to develop.

The specimen displays a predominantly light white to cream coloration with naturally developed crystal aggregates and a soft pearly to vitreous luster. Stilbite is well known for radiating, sheaf-like and bow-tie crystal aggregates, while Heulandite commonly forms tabular or wedge-shaped crystals with attractive luster.

Comparable collector specimens from Pune District and other Maharashtra localities are documented with Stilbite and Heulandite occurring together, confirming this as a classic Indian zeolite association.

Measuring approximately 7 × 7 × 4 cm and weighing 90 grams, this is a compact collector-size mineral specimen suitable for a display cabinet, zeolite collection, geology collection, or natural mineral display.

Natural variations in crystal size, luster, transparency, inclusions, contact areas, minor chips, and irregular crystal growth are part of the specimen's geological character.
